The ISL88003IH31Z-TKis a latest advanced PMIC - Supervisors. It is designed for use in the harsh environment of industrial applications, and it offers superior protection against abnormal supply voltages, short circuits, and other resistive faults. By combining precision, low-power and low standby current, the ISL88003IH31Z-TK is able to extend battery life and protect sensitive electronic systems from over-voltage and other disasters. Its features include adjustable threshold, low input/output voltage, build-in EMI filter and programmable time delays.

The primary application field of the ISL88003IH31Z-TK is industrial control systems, electric vehicles, battery-powered applications, consumer electronics and more. It’s ideal for applications that require high reliability and failsafe operation. For example, it can be used to protect lithium cell battery packs in electric vehicles.

The working principles of the ISL88003IH31Z-TK are pretty straightforward. It has two independent input channels that monitor the positive and negative terminals of a system supply. When the input voltage of either channel crosses the threshold, defined by adjustable external resistors, the device provides a logic-level output. This output can be used to trigger an external circuit such as power MOSFETs, optocouplers, etc.

In addition, the ISL88003IH31Z-TK has reverse polarity and ESD protection. Reverse polarity protection prevents the device from damage when the power source is connected to the wrong terminals. ESD protection is important, particularly when the device is used in portable applications. It prevents electrostatic discharge from causing damage to the circuitry and components.

The ISL88003IH31Z-TK also offers adjustable delay time to allow for time interval between an input transition and an output transition. This can be useful, for example, when powering up systems with short-circuit protection or when controlling power-up/ power down sequencing. Moreover, it features programmable standby current and wide input voltage range, from 3.5V to 42V, allowing for great flexibility.

Finally, ISL88003IH31Z-TK is one of the most advanced PMIC - Supervisors on the market. It is designed for use in harsh environments and features robust protection, adjustable settings, low input/output voltage and adjustable time delays. In addition, its ESD and reverse-polarity protection ensure reliable operation and reduce the risk of device damage. All of these makes the ISL88003IH31Z-TK ideal for industrial control systems, electric vehicles, battery-powered applications, consumer electronics and a whole range of other applications.
